Syntax

wpSet = addCorrespondences(wpSet,viewId,pointIndices,featureIndices)
wpSet = addCorrespondences(wpSet,viewId,pointIds,featureIndices)

Description

wpSet = addCorrespondences(wpSet,viewId,pointIndices,featureIndices) adds correspondences between 3-D world points and 2-D feature points to the world point set wpSet, using the point indices pointIndices and the feature indices featureIndices for the specified view viewId. Use this syntax if you added points using the addWorldPoints function without specifying unique point identifiers pointIds.

example

wpSet = addCorrespondences(wpSet,viewId,pointIds,featureIndices) adds correspondences between 3-D world points and 2-D feature points to the world point set wpSet, using the point identifiers pointIds and the feature indices featureIndices for the specified view viewId. Use this syntax if you added points using the addWorldPoints function by specifying unique point identifiers pointIds.

Open Live Script

Generate 3-D world points.

worldPoints = rand(100,3);

Create a worldpointset object.

wpSet = worldpointset;

Add world points.

wpSet = addWorldPoints(wpSet,worldPoints);

Add correspondences to View 1 for the first 10 points.

viewId = 1;
pointIndices   = 1:10;
featureIndices = 1:10;
wpSet  = addCorrespondences(wpSet,viewId,pointIndices,featureIndices);

Input Arguments

collapse all

World point set, specified as a worldpointset object.

View identifier, specified as a scalar.

Identifiers for 3-D points in wpSet, specified as an M-element row vector of integers.

World point indices, specified as an M-element column vector of integers. M is the number of world points for which you are adding correspondences.

Feature point indices, specified as an M-element column vector of integers. M is the number of world points for which you are adding correspondences.
